Other Parts Discussed in Thread: TPS61165

Hi Team,

For TPS61165, do you see any negative effect adding one small cap, like 470pF or 1nF, in paralleled with the ISET resister ? Especially during start-up ?

Customer now using Easy-scale dimming method.

Thanks for your help in advance.

Hi Team,

Could you help for below topic ?

Also, another problem, could the VIN pin be supplied separately like 5V, while the power rating input from another higher input 12V (spike could be 20V, higher than 18V max of TPS61165)?

Is there any power sequence required or concern ?

Thanks.
